Background
In 1976, Mercedes-Benz introduced the W123 executive saloon to replace the most successful selling Mercedes to date, which was the W115. With a more contemporary look, the W123 had a longer wheelbase, round headlights, and a less angular look on the styling side of things. Later in the European production the headlights were changed to rectangular units.
Powering the W123 was the 3.0-llitre 5-cylinder engine from the W115, with the 240D model renamed to the 300D to match the North American markets. The reliability of the engine and the over engineering of the W123 made the car a popular choice for the German taxi businesses, with the cars covering 300,000 miles plus with ease. Many soldiered on to double that figure.
Missing from the range was an estate variant, so in 1978 Mercedes introduced the W123 T, built at the Frankfurt factory. In fact, it was the company’s first ever estate car, as surprising omission. Topping the range was the 300TD, the T standing for transport and touring and of course the D for diesel power.
The 300TD was undoubtedly a luxurious car, capable of seating up to seven people if the optional third row of seats was fitted.
By the early ‘80s, a raft of safety features was added which included Anti-Lock brakes. More comfort orientated features were to appear to, with power steering, cruise control and central door locking now standard features.
Production of the W123 ended in 1985 and many consider this to be one of the best car Mercedes-Benz ever built. We would be inclined to agree.
